Dual coil subs
 

ok i have a dual coil rf sub (250 watts rms) I have a 2 channel rockford amp that can push out 250 watts rms bridged, or 75 watts rms per channel.

Should I: parrallel the coils together and hook them up to the amp bridged, so the sub can meet its full potential of 250 watts or hook each individual coil to a channel at 75 watts a channel.

I will be hooking it up the first method, unless there is some reason not to.

thnx

Hooking the coils up to different channels wouldn't be a very good idea. Go with option 1 as you said.

^^^^^ say what? If your sub is a dvc 2 ohm sub then wire it in series and bridge the amp. If it is a dvc 4 ohm sub then it is not ideal to operate the amp in bridged mode with the sub wired in parallel as 99% of the time this is beyond the amps ability to operate safely. The safe route is indeed wiring one coil to each channel or preferably to wire the sub in series to 8 ohm and onto the bridged outputs of the amp.

option number one of running the sub in parallel bridged will work ONLY if the amp is stable to 2 ohm's

Maybe my idea of a two-channel amp is wrong... by wiring two coils of the same sub to different channels aren't you giving it two different signals, like "left" and "right"?

i have read the manual an 4 ohms is min impedance for bridged, so i will series the coils and bridge at 8 ohms.

thnx for input

Technically yes. Reality is that most often there isn't a whole lot of difference between the left and right channels down in the bass region.

Gotcha.
